' KRoscHEL', ADMINISTRATRIX, or ALBANY, OREGON BUILT-11v FURNITURE Substitute of application Serial No. 107,155, filed May 6, 1926.

Serial No. 364,668.

This invention relates to 'Wall and built-in furniture and especially to means for fold-' ably connecting a board, table or seat element to a Wall or wall cabinet.

An object of the present invention is to Another object is to provide a foldable, wall furniture -unit embodying a table or board element which, While having but a,

single central, channel iron, foldable strut, is so stabilized as to be very rigid.

Another object is to provide a wall furniture unit of low cost of installation.

Another object is to provide means facilitating folding and unfolding of the element."

An object is to provide a furniture unit which is self-locking when extended.

Other objects and advantages will. be made manifest in the ensuing specification of apparatus embodying one form of the invention; it being understood that modifications,- variations and adaptations may be resorted. to within the spirit and scope of the lnvention as it is here claimed.

This application is a substitute for applithe element 11 in strut 2-8. e I 7 When it is desired to break the knuckle cation number 107,155, filed May 6, 1926.

Figure 1 is a plan of the extended table a; element, of a unit, broken away between sides.

Figure 2 is a side elevation of the extended table; the wall cabinet being in section.

Figure 3 is a cross-section showing the sta- -:i bilizer of the table board in elevation.

Figure 4 is a cross-section of the stabilizer; Figure 5 is a cross section of the folded and nested link of the main strut.

It has long been the practice to provide a board member or element with trunnions ex-. tending from one end and slidable in slots or vertical runways and to support the board in a horizontal position by various braces.

The present invention aims to provide means for stabilizating the extended board While it is supported on a single centrally mounted folding strut or arm.

The new brace comprises a bottom channel-iron link 2 having a cross-pin or pivot i 50 3 in bearing ears 4 fixed on a solid sill or base ,stop finger on. section 12,

.tions are opened past center line.

This applicat ion fi led May 20, 1929.

5, which is suitably disposed in a cabinet 6 into the front plane of whichthe board, seat or table, as the casemay be, is foldable flush.

The outer end of the link 2 fits between side i tongues 7 formed by cutting away the web of the channel link 8 and'a pivot.pin.9 c011 nects the links 2 and 8 so thatthe former can be folded close, in nested position, on link 8 as shown in Figure 5, when the links are buckledand swung up to a closed vertical position on the cabinet recess.

The outer end of link 8 is pivoted at 10 i to the outer endof an element 11, here shown as a table or ironing board. 1

When the element '11 isextended in horizontal position it is rigidly braced by means of a sec0ndaryt1'uss comprising a'knucklejointed link having a section 12 hung on pivot pin 9- and pivoted. at 13'to'the near end of section 14 which is overlapped by a when the sec- Section 14 is pivoted at 16v on the element 11 and when the latter is foldedout the primary two-piece strut 2-8 straightensoutand pullsthe knuckle-brace 12-14 out straight,

andthis latter forms a firm support holding given angle as to primary truss 12 -14 a reach rod18 connected at '19 to the section '14 is pulled forward in its bearing 20 (under theelement 11). This allows the main strut to knuckle up and the outer end of the element 11 swings down.

A spring 21, connecting section 14 and the element 11, tends to automatically lock the knu'ckletruss in efiectifve position as the element 11; is extended. r

It is understood that the element 11 may be 'foldablyrelated to the'cabinet 6 in various ways.

As here shown the rearend of the table element 11 has a transversetrunnion.piece whose ends slide snugly inguides'26 atthe Isid'e'of cabinet 6(s0' that while the inner end .of' the table .11. may slide-11p anddown it cannot-pull forward;

A feature. of 4 this invention l consists of .Q means to. stabilize the horizontal :table and loo prevent its being tilted down at either side While it is supported only by the narrow, centrally disposed primary linked channels 2-8.

The stabilizer comprises a cross-beam 27' of a length and Width to closely run in the guides 26. The beam 27 has bearing straps 28 fitting the rounded trunnion part 25 and swinging thereon when the table is moved, To obtain bracing efi ect the beam 27 has such depth that it binds endivise against the bottoms of the guides 26 When there is any titlting side pressure applied to the extended table, this binding action being indicated the dotted lines a-b, Fig. 3. t

A suitable spring 30, attached at one end to the inner end of the table, and at its lower end of a fixed point 31 back of pivot 3 of the link 2, tends to pull the table, when upright, back against the stop formed by the bearing 4, the point 31 being back of the pivot 3.

A footlever 33 is provided on a rock shaft at having a presser arm 35 acting against the back of the link 2.

When footelever 33 is pressed 7 down it causes lever 35 to press the link 2 out and down and thus aid in starting the table from upright position in the cabinet 6.

The dotted lines in Fig. 2 indicate folding action of the table and links. 7

The Web of the top link-8 is cut back at each end toform side lugs for a pivot pin. Thus the link is fully reversible in assembly of the parts.

What is claimed is:

1. Wall furniture having, in combination, a set of guides, a board having trunnions sliding along in said guides, and a stabilizer connected to the board and having ends running in the guides and preventing side tilting of the board.

2. Wall furniture having, in combination, a set of guides, a board having sliding trunnions in. cooperative relation with said guides, and means connected to said trunnion-and operating in the guides to prevent tilting of the board sidewise; said means including a crossbar extending from guide to guide.

3. The combination With a folding table member of single, centrally disposed folding bracket structure comprisinga 'bearing'fixed to a sill, alink member having its fulcrum on said bearing, alinksection pivoted on the outer end of the link :member and alining therewith When extended, said section bein pivoted at-its outer end to the board member, 7

aknuckle-joint brace oneend of which is piv oted on the pivot connecting the brace link andthe link section, the opposite end of said :knuckle brace being attached to the board member, a springconnected-to the board and knuckle brace for opening thezknuckle brace intman effective position, a manual pull rod connected to one element of the knuckle-brace :tQ tbreak it, and a foot treadle idmhmwing tthe 1 bracdstructure forward into a support-1 ing position, including a lever arm slidingly attached to the brace member; said link member, said section, and said knuckle brace all being substantially in a common plane.
